Kitchen double door freezer

Forced circulation of cold air: also known as intercooler (air-cooled) or frost-free refrigerator. There is a small fan in the refrigerator, which can make the air flow in the box, the temperature in the box is even, the cooling speed is fast, and it is easy to use. However, due to the defrosting system, the power consumption is slightly higher and the manufacturing is relatively complicated.

Cold air natural convection: also known as direct cooling or frost refrigerator. The freezer is closed directly by the evaporator, or there is an evaporator in the freezer. In addition, the evaporator is arranged in the upper part of the freezer, and the evaporator absorbs heat directly for cooling. The structure of the refrigerator is relatively simple, the power consumption is small, but the temperature efficiency is low, the use is relatively inconvenient.

Cold air forced circulation and natural convection combined use: this type of refrigerator new products are mostly used, mainly to consider the advantages of air cooling and straight ice box.
